You seem to have a knack for colors and composition, and your photos aren't half bad--all that's left is getting a custom style, like the other guys said. I dunno how anybody else started, but I first based custom torsos off of preexisting sets, like Brutaka. Then I systematically began finding ways to make little bits more and more compact and complicated, and shazahamapow. Custom torso. You should definitely take notes from other builders like 'Gat said, but make sure to remain true to your own style, because when you find yourself with no internet and a whole lotta parts, you should be able to make something you're really proud of.

If you want to try out a few custom designs, the best way to do it is to copy others' designs and get a feel for it. So long as you give people credit, it's a great way to learn, and contrary to popular belief, a lot of people WANT their designs to be used by other people :P I suggest trying to find a more practical way to attach his shield to his arm, as well.

I tried trying out making my own custom body, but it sucked. I'll try to make a custom body in LDD. (I tried making the body of Chronos Omega's self-moc. But since I had trouble making it, I quit the design.) Thanks any way.

The pic with his shield hitting the ground, uber cool. nice self-MOC btw, though I would have to suggest trying out custom bodies, inika builds don't usually get a lot of traffic here on MOCpages(Some people think it's a disease) but it's difinently a good first version for your self-MOC, keep building and improving, I can't wait to see more!

Thanks Era, though I must admit that I'm not that good at making custom bodies. Just custom arms and legs. But I can make an advanced version of it in LDD.
